Strap for Arkade White Gold - Diamond / Diamond

The A. Lange & Söhne Arkade 801.039 features a lug width (ansa) of 14 mm, which corresponds to the internal distance between the spring bars that support the strap. This is a standard specification for smaller timepieces such as this 29 mm case diameter example. To verify the lug width with precision, measure the distance between the two spring bars: it should be exactly 14 mm.

For the Arkade 801.039 in white gold, the most recommended materials are alligator, calf leather, and shell cordovan, all with vegetable tanning. Intense black alligator creates formal contrast and emphasises the brilliance of white gold; light brown or cognac calf leather introduces warmth whilst maintaining elegance; wine-coloured shell cordovan offers natural lustre and aesthetic dynamism. The ideal strap thickness should fall between 3 and 4 mm to avoid visually overwhelming the wrist.

Strap replacement is achieved by removing the spring bars from their respective holes in the case. Use a specialist tool, preferably a professional spring bar tool, to gently lift the spring bar catch and slide it out of the lugs. Repeat for the second spring bar, then remove the worn strap and insert the new one, ensuring both spring bars are firmly positioned in the lugs. For luxury watches such as the Arkade 801.039, professional horological services are recommended.

Yes, high-quality aftermarket straps compatible with the Arkade 801.039 are available thanks to the standard 14 mm lug width. Straps manufactured by specialised houses in noble leather — alligator, vegetable-tanned calf, shell cordovan — guarantee both mechanical and aesthetic compatibility. It is essential to verify that the strap is specifically designed for the 14 mm lug width and that thickness does not exceed 4 mm, to preserve the visual proportions of the 29 mm case.

The lifespan of a leather strap depends on material, frequency of wear, and maintenance. An alligator or vegetable-tanned calf strap, worn daily, has an average lifespan of 4–7 years before the leather begins to show signs of wear. Shell cordovan, thanks to its denser fibrous structure, can last 8–10 years or longer. Regular maintenance — gentle cleaning with a soft cloth, rapid drying if exposed to moisture, and annual conditioning with specialist creams — significantly extends the strap's useful life.
